The authoritarian mindset really really believes that they can make better decisions than everyone else. Worse, those closest have unending incentive to cheer this on because once again this is tee source of all present largesse.
The difficulty is that it also naturally severs the communications necessary for the rest to prosper and stagnation becomes inevitable. China has had the luxury of yusing fiat currency expansion to agressively expand the economy and we now have the living standards of the base expanding. The size of the problem was so huge that it took all of thirty years.
At this point the holiday appears to be over. Yet the same mindset is grasping to assert control in Hong Kong. This is almost independent of the economic expansion and is more a study in opportunism. It is been opposed and frankly, as no good can be expected from acceptance, it needs to be opposed strongly.
Thus we see the demos speak in Hong Kong.
